Because the PLLD transducer must be installed downstream from these devices,a monitored containment <br /> sump is required. <br /> Also, there must not be a check valve installed between the SwiftCheck valve] and the pump for PLLD to function <br /> properly. <br /> Refer to Figure 4-13 for PLLD installation with a Healy Mini-Jet system.Follow the applicable guidelines of"Installing <br /> the SwiftCheck Valve"on page 4-11 and"Installing the PLLD Transducer"on page 4-2. <br /> Ensure that the Healy pump is wired according to the manufacturer's instructions and utilizes isolation relays. <br /> Submersible HealyTM <br /> pump Mini-Jet <br /> Containment PLLD sensor I <br /> sump Dula D` <br /> \\ \SwiftCheck valve Product line <br /> to dispensers <br /> —Red Jacket leak <br /> detector fitting <br /> — (Red Jacket Part# <br /> 038-072) <br /> 'I <br /> Sump <br /> sensor <br /> Note:remove inline check valve, <br /> if present <br /> puauceay.a� <br /> Figure 4-13.
